I avoided posting in this thread or filling out the poll because I did not know how to answer.
I like
@osprey's comment above about experience. There is a big difference between exposure and experience. I have a lot of exposure, but little real-world experience with Linux. I am especially inexperienced with the desktop aspects, and really appreciate the help I have received from the other members who have generously answered my dumb questions.
My first exposure to Linux was in the 1990s. My friends/coworkers and I used to copy and share CD ROMs with Linux. I remember Slackware for Intel PCs, but I don't remember if another version of Linux preceded it. For PowerPC, there was MkLinux, followed by LinuxPPC. (Everybody was eager to get their hands on that first MkLinux. The originals were handed out at a conference and it took time for copies to trickle down to us.)
Since then, I have always had Linux available in a virtual machine or a VPS. (In fairness, I have Windows VMs, too.) To be clear, Linux was never my primary desktop computer. That may change in the future and I am already planning for it.
Some people are passionate about their choice of operating system. I am not. I tend to see the similarities between them and not notice the differences in how the user interacts with them. In general, I know enough to "get the job done" regardless of which operating system is thrust in front of me on the screen. I do not like that humor thread here that is full of cartoons bashing non-Linux operating systems. I would rather be respectful and supportive of others' choices, Linux or not.
